5G mobile broadband will see more carriers deploying this technology in more locations whether as a trial setup or to run with it as a full revenue service. It will also see the arrival of client devices like smartphones or laptops rather than just USB modems or modem routers supporting this technology.

Some users will see 5G mobile broadband as supplanting fixed broadband services but the fixed broadband technologies will be improved with higher data throughput that competes with that technology. As well, fixed broadband especially fibre-based next-generation broadband will also be required to serve as an infrastructure-level backhaul for 5G mobile broadband setups.

Wi-Fi 6 a.k.a. 802.11ax Wi-Fi wireless will be officially on the scene with more devices becoming available. It may also mean the arrival not just of new access points and routers supporting this standard but the arrival at least of client-side chipsets to allow laptops, tablets and smartphones to work with the new technology. Some countries’ radio-regulation authorities will look towards opening up the 6GHz spectrum for Wi-Fi purposes.

It also runs alongside the increased deployment of distributed-Wi-Fi systems with multiple access points linked by a wired or wireless backhaul. This will be facilitated with Wi-Fi EasyConnect and EasyMesh standards to create distributed-Wi-Fi setups with equipment from different vendors, which means that vendors don’t need to reinvent the wheel to build a distributed-Wi-Fi product line.

LG 4K OLED TVs – a technology that could be coming more affordable over 2019

4K UHDTV with HDR technology will head towards its evolution phase with it maturing as a display technology. This will be with an increased number of sets implementing OLED, QLED or similar display technologies. It will also lead to more affordable HDR-capable TV models coming on to the scene.

Screen sizes of 75” and more will also cut in to affordable price ranges/ This will also be augmented with OLED-based screens becoming available in a “rollup” form that comes in an out like a blind or a traditional pull-down screen. Similarly, there will be a look towards the concept of “visual wallpaper” in order to justify the use of large screens in peoples’ households, including using the screen as a way to show messages or other information.

Online services will still become the primary source of 4K HDR TV content but the 4K UHD Blu-Ray disc will increase its foothold as the “packaged collectable” distribution medium for 4K video content. ATSC 3.0 and DVB-T2 will be pushed as a way to deliver 4K UHDTV content over the traditional TV aerial with this method of TV reception regaining its importance amongst the “cord-cutting” generations who dump cable and satellite TV.

More of these voce-driven home-assistant devices with screens over this year

Another major direction affecting the home network and consumer electronics is an increased presence of voice-driven home-assistant services in this class of device. Typically this will be in the form of soundbars, wireless speakers, TV remote controls and similar home-entertainment equipment having endpoint functionality for Amazon Alexa or Google Assistant.

As well, the “smart screens” like what Lenovo, JBL and Amazon are offering will become more ubiquitous, with the ability to augment responses from a voice-driven home assistant. It will be part of having more household appliances and other gadgets work tightly with voice-driven home assistants.

It may be seen as an effort to bridge the multiple network-based multiroom audio platforms so you can run equipment from different vendors as part of one system. But the problem here will be that such setups may end up being more awkward to use.

The smartphone will be facing some key challenges what with people hanging on to these devices for longer and / or running two of them – one for their work or business along with one for personal life. Some new form-factors like folding smartphones will be demonstrated while some of them will be optimised for high-performance activities like gaming.

These devices are being augmented with the return of mobile feature phones or basic mobile phones. These phones are like the mobile phones that were on the market through the 1990s and 2000s and don’t connect to the home network or Internet or use these resources in a very limited way. They are appearing due to people wanting detachment from online life like the Social Web usually as part of the “back to basics” life calling, or simply as a fail-over mobile telephony device.

But as laptops and tablets become full-on computing and communications devices, the feature phones and basic phones will simply work in a complementary way to allow voice telephony or text messaging on the same service in a handheld form.

This situation is being underscored by more mobile carriers offering mobile telecommunications services that aren’t necessarily bound to one particular device. This is to face realities like the connected car, smartwatches with mobile broadband, Mi-Fi devices amongst other things which will be expected to use the same mobile service.

In the same context, there will be a market requirement for mobile communications devices, especially mobile phones, to support two or more services including multiple numbers on the same service. Primarily this will be driven by eSIM technology and over-the-air provisioning, but it will facilitate ideas like totally separate services for one’s business and private lives, or to cater towards people who regularly travel across international borders.

Security and regulatory issues

I do see a strong push towards more secure Internet-of-Things devices for residential, commercial and other applications over this year. This is as regulators in Europe and California put the pressure on IoT vendors to up their game regarding “secure-by-design” products. There is also the expectation that the Internet Of Things needs to be fit for purpose with transport applications, utilities, medical applications and the like where there is an expectation for safe secure reliable operation that cannot be compromised by cyber-attacks.

Here, it may be about the establishment of device-firmware “bug-bounty” programs by manufacturers, industry bodies and others used to unearth any software weaknesses. Then it will lead towards regular maintenance updates becoming the norm for dedicated-purpose devices. It may also include a requirement to for device vendors and end-users to support automatic installation of these maintenance updates but allow for manual installation of major “feature-addition” updates.

This is in conjunction with the Silicon Valley behemoths like Amazon, Facebook, Apple and Google having to change their ways due to them under increased scrutiny from governments, media, activist investors, civil society and end-users. It will affect issues like end-user privacy and data transparency, financial and corporate-governance / human-resources practices, along with the effective market power that they have across the globe.

Equipment design

Use of Gallium Nitride transistors for power conversion

A major trend to see more of this year is the increased use of Gallium Nitride transistor technology. This is beyond using this chemical compound for optoelectronics such as blue, white or multicolour LEDs or laser diodes installed in Blu-Ray players and BD-ROM drive for the purpose of reading these optical discs.

Here, it is to multiply the effect silicon had on the design of audio equipment through the 1970s leading to highly-powerful equipment in highly-compact or portable forms. This is through improved heat management that leads to the compact form alongside more powerful transistors for switch-mode circuits.

One of the initial applications will be in the form of highly-compact USB-C Power-Delivery-compliant chargers for laptops and smartphones. This year will be about an increased number of finished products and reference designs that, depending on the application,  yield more than 45W of DC power for USB-C PD applications from either 100-250VAC mains power or 12-24VDC vehicle / marine power. It could then be affecting multiple-outlet “charging bars” and similar devices where the goal is to have something highly compact and portable to power that Dell XPS 13 or Nintendo Switch alongside your smartphone.

I see it also affecting how power-supply circuitry for computers, peripherals, network equipment and the like is designed. This can lead towards equipment having the compact profile along with reduced emphasis on factoring in thermal management in the design like use of fans or venting.

ARM-based microarchitecture to compete with Intel’s traditional microarchitecture

In the late 1980s, the then-new RISC (Reduced Instruction Set Computing) microarchitecture excelled with graphics and multimedia applications. This is while Intel’s x86-based 16-bit traditional-microarchitecture used in the IBM PC and its clones were focused simply on number-crunching.

But 32-bit iterations of the x86 microarchitecture were able to encroach on graphics and multimedia since the early 1990s. Eventually it led to Apple moving the Macintosh platform away from the RISC-based Motorola CPUs towards Intel-based x86 and x64 traditional microarchitecture.

This was while Acorn Computers and a handful of other computer names worked towards ARM RISC microarchitecture which ended up in smartphones, tablets, set-top boxes and similar applications.

Now this microarchitecture is making a comeback with the Always-Connected PCs which are laptops that run Windows 10 on Qualcomm ARM processors for higher power efficiency. It was brought about with Microsoft releasing a Windows 10 variant that runs on ARM microarchitecture rather than classic microarchitecture.

This will lead to some computer vendors running with at least one or two of these computers in their ultraportable product ranges. But there is investigation in to taking ARM technology to higher-power computing applications like gaming and server setups.

The big question for Intel is what can they offer when it comes to microprocessor technology that can answer what Qualcomm and others are offering using their ARM processors.

Increased SSD capacity

The solid-state drive will start to approach bill-of-material per-kilobyte price parity with the 500GB hard disk. Here, it could lead towards laptops and ultra-compact desktop computers coming with 512Gb SSDs in the affordable configurations. This is also applying to USB-based external storage devices as well as what is integrated in a computer.

Here, the concept of high-speed energy-saving non-volatile storage that would satisfy a “sole computer” situation for a reasonable outlay is coming to fruition. What will still happen with the traditional mechanical hard disk is that it will end up satisfying high-capacity storage requirements like NAS units or servers. In some situations, it may lead towards more NAS units supporting multi-tier storage approaches like bring frequently-used data forward.

Conclusion

This is just a representative sample of what 2019 is likely to bring about for one’s personal and business online life, but as with each year, more situations will crop up over the year.

Are we to expect laptops to be mobile phones?

My Comments

An increasing trend we are seeing with regular desktop and laptop computers is that they are being used for voice and video telephony. Thu is being driven by messaging apps of the Skype, Facebook Messenger, WhatsApp and Viber kind being ported to desktop operating systems; along with softphone applications that provide telephony functionality being made available for these operating systems. The softphone applications, along with Skype are even legitimising this usage case with laptops in the business environment turning them in to secondary or replacement phone extensions.

Headsets like the JBL E45BT Bluetooth headset are used with laptops to make voice calls with messaging apps and soon this will happen for mobile telephony

With these setups, you can talk with the caller using the computer’s integrated or attached microphone and speakers. Or, should you want the same level of privacy associated with holding a handset up to your ear, you can talk to the caller using a wired or Bluetooth headset, of which I have reviewed many on HomeNetworking01.info.

Microsoft and others in the “open-frame” computing world are pushing along with the Always Connected PC which runs ARM RISC microarchitecture rather than the traditional Intel-based CISC kind. These ultraportable computers will also be equipped with a wireless broadband modem that is authenticated using eSIM technology.

The idea is to eventually have these computers become like a smartphone with them linked to the cellular mobile network. It is also alongside the fact that today’s smartphones are effectively pocket computers running a mobile operating system.

It could be easy to say that the Always Connected PC concept is irrelevant because one can “tether” a computer to a smartphone to have access to the mobile broadband service, whether through a USB connection or a Wi-Fi-based “hotspot” function that mobile operating systems support. Or we can simply connect our computers and phones to Wi-Fi networks including publicly-accessible networks like hotspots. For that matter, computers can also be connected to other network types like Ethernet or HomePlug AV networks.

Smartphones now are pocket computers

Let’s not forget that the GSM Association and the Wi-Fi Alliance are looking at Wi-Fi networks as a way of providing data-offload functionality. This is through mobile carriers like BT and Telstra offering FON-style community Wi-Fi networks and the Wi-Fi Alliance using Passpoint / Hotspot 2.0 as a way to provide hands-off login to public-access networks.

The Wi-Fi functionality is also being taken further in the context of smartphone-based voice telephony with the use of VoWLAN as another call-transport option for these devices. Some mobile telcos like Telstra even use this as a way to provide voice telephony continuity to their customers if they can’t reach the cellular network but can use Wi-Fi-based Internet.

The focus now is towards the concept of always-connected portable computing with a secure and consistent connectivity experience. This is being brought on through the use of 5G mobile-broadband technology and the interest in edge computing which provides support for localised data processing and storage in a cloud environment.

The eSIM is being pitched as a way to provision mobile service in an online manner, especially to vary the service to suit one’s needs or switch to a competing mobile telco. It also is placing pressure upon mobile telcos to adopt a “service-focused” approach with the idea of having multiple devices on the same mobile account and plan, ringing to the same mobile number and using the same data allowance. The goal with mobile telephony will then be to make or take a voice or video call or send and receive messages on the device that you currently are using rather than changing to a different device for that task.

Connected cars even to be another logical device for one’s mobile service account.

This concept has been driven by the Apple Watch and will be pushed on with smartwatches that have built-in mobile broadband modems. But it will be extended through other devices like smartphones, Always Connected PCs and connected vehicles. There is also the idea of implement the equivalent of a local area network across devices tied to the same service and this will be driven by the trend towards ubiquitous ambient computing.

A question that will come about is the ability to maintain multiple different services on the same physical device whether from the same telco or different telcos. This will be about maintaining separate services for business and private use. Or it could be about travellers who want to maintain a local service while at their destination along with their “home” service. This is a feature that is of relevance in countries where cross-border commuting is the norm thanks to land borders or short affordable ferry rides.

This could be addressed through support for multiple services including the ability to provision a cluster of multiple devices with the one service simultaneously. This same issue can also address the ability for us to use the conventional Internet service based around a hardwired broadband service with a Wi-Fi and / or Ethernet local network in the premises.

What I see out of this new trend is that if your computing device has mobile broadband or connection to the Internet via a local-area network, along with a speaker and microphone, it will become the one-stop computing and communications device. It doesn’t matter what shape or size it is in, being a smartphone, laptop or whatever. As well, the right-sized computing device will serve your computing and communications needs as you see fit.

My Comments

A trend that will have an impact on devices that use cellular-based wireless broadband technology is for them to implement eSIM authentication.

What is the eSIM technology?

It is effectively an embedded SIM which is a hardwired equivalent of the SIM card that authenticates you to a mobile-telephony / wireless-broadband service as a customer.

One of the key advantages to this approach over the traditional user-replaceable SIM card is that there isn’t a need to design a large user-accessible space in a mobile device to accommodate one of these cards. Instead, the customer’s wireless-broadband service is provisioned to their device “over the air” rather than having to encode a SIM card to hand over to the customer to be installed in the device. It is similar to the online provisioning and service activation process implemented for some prepaid mobile-telephony / wireless-broadband services sold through ordinary retailers in some markets.

What devices will this appeal to?

This approach appeals to the wearables market where size does certainly matter but is also appealing towards the connected car where there isn’t a desire to create a cavity for a SIM to be installed. Just lately, the eSIM technology is also appealing to the “always-connected” ultraportable laptops thanks to the next major functionality iteration of Windows 10 having software support for this functionality baked in.

Let’s not forget that newer smartphones, USB modems and MiFi routers including multiple-WAN routers will become equipped with eSIM support, especially where multiple-service functionality is to be part of the feature set. It could allow one to design, for example,  an Android smartphone with a classic SIM slot and an eSIM along with a microSD card slot. Here, a user could then benefit from the advantages of multiple services while using a microSD card to provide “infinite” storage for music, photos and videos.

The main disadvantage that the eSIM will offer to some people will be that they can’t switch SIM cards around quickly, which may be of concern with people using a “decoy” number associated with a prepaid service or people who are troubleshooting mobile devices.

What does this allow?

It was brought on board in 2013 but recent improvements to the eSIM standard allowed for a customer to maintain multiple eSIM services from the same or different carriers in the one device. It is similar to how users are switching SIM cards around to maintain multiple service accounts, such as to maintain separate “business” and “private” services, to sign up with “destination-local” mobile-telephony services with a “destination-local” number and payment options, amongst other reasons.

This provides simplification for these users by providing “over-the-air” provisioning for additional services including varying these services or re-instigating dormant services. The user-experience that may be offered is to choose the network that provides the service you want to use then enter an activation code of some sort to “turn on” that particular service. Typically this would be something you receive in an email if you are enrolling online or receive from a staff member at a “bricks-and-mortar” store.

Some carriers and service providers are exploiting eSIM by offering a “one number one account multiple devices” option for their mobile services such as Telstra’s “One Number” service. But there are other ways that mobile-telephony service providers can exploit the emerging eSIM setup. But the carriers can look at exploiting the eSIM further such as tying it in with BYOD business setups, mobile services that can be “parked” when not needed amongst other things.

In some business environments, it could allow a single shared device to be associated with multiple service accounts with the accounts in operation dependent on who is logging in to the device. This could tie in with the “portable desktop” approach towards business telecommunications where one’s computing and telecommunications setup is moved amongst multiple devices but your boss or clients call you at the same extension number.

Conclusion

The eSIM approach for authenticating mobile-telephony and broadband service can open up a wide range of approaches both for device design and for service delivery.
